%X The Stephani universe is an inhomogeneous alternative to ¦«CDM. We show that the exotic fluid driving the Stephani exact solution of Einstein¡¯s equations is an unusual form of k-essence that is linear in ¡°velocity¡±. Much as the Stephani universe can be embedded into (a section of) flat 5-d Minkowski space-time, we show that the k-essence obtains through dimensional reduction of a 5-d strongly coupled non-linear ¡°electrodynamics¡± that, in the empty Stephani universe, corresponds to space filling magnetic branes in string/M-theory.
